Next, when the strap (rear strap) 56 is pulled as shown by an arrow b4, the lock of the seat backward support mechanism 22a is released. Therefore, if the strap (rear strap) 56 is further pulled, the seat device (three rows) The eye sheet) 22 rotates backward as indicated by an arrow a5.

  When the seat device (third row seat) 22 rotates rearward, the back support leg 55 is placed on the rear wall 58 that is open and waiting, so that the seat back 37 is supported by the back support leg 55, and Loads such as added weight and weight of the load can be distributed to the rear wall 58.

When returning the seat device (third row seat) 22, when the seat back 37 is raised to the seat back standing posture position 41, the seat reverse support mechanism 22 a automatically moves the seat device 22 at the seat back standing posture position 41. Since the locking is performed, the seat device 22 is fixed to the floor 74. In the case of a structure in which the cushion leg 95 is locked, the cushion leg 95 is locked.
Subsequently, when the switch 116 is pressed, the rod 114 of the cylinder 112 moves forward (in the direction of the arrow s2), so that the rear wall 58 is closed.

  The sheet storage device 24 also exhibits the same operation and effect as the one-seat sheet unit 88 for the two-seat sheet unit 91.

Next, the storage mode will be described.
In the storage mode, as shown in FIG. 6, the sheet device 22 is stored in the storage recess 31. The back support leg 55 is not rotated as shown by the arrow a3.

  When the tailgate 16 is opened from the outside of the vehicle 11 and the strap (rear strap) 56 is pulled as shown by the arrow b6, the cushion leg 95 is unlocked from the floor 74. Therefore, when the rear strap 56 is further pulled, the seat The cushion 36 and the seat back 37 are folded and overlapped. When the rear strap 56 is pulled, the reclining device 43 puts the seat back 37 into a free state.

When the rear strap 56 is gripped and pulled, the seat device 22 rotates to the position indicated by the solid line in FIG.
When the sheet device 22 is pushed in at a position indicated by a solid line in FIG. 6, the sheet device 22 is stored in the storage recess 31. And if the rotation support mechanism 27 is pushed, it will fall down (refer FIG. 3, FIG. 5).
